Calibrachoa plant named ‘SAKCAL104’

ABSTRACT

A  Calibrachoa  plant particularly distinguished by having a pink flower color and a compact plant growth habit, is disclosed.

Genus and species: Calibrachoa spp.

Variety denomination: ‘SAKCAL104’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Calibrachoa plant, botanically known as Calibrachoa spp., and referred to by the variety name ‘SAKCAL104’. ‘SAKCAL104’ originated from a hybridization in Kakegawa, Japan in 2006 between the female Calibrachoa line ‘6dw-54B’, an unpatented proprietary hybrid Calibrachoa breeding line having a rosy red flower color and compact growth habit and the male Calibrachoa line ‘5Bdw-70A-1C’, an unpatented proprietary hybrid Calibrachoa breeding line with a white flower color and compact growth habit.

In November 2006, the female parent line ‘6dw-54B’ and the male parent line ‘5Bdw-70A-1C’ were crossed and 150 seeds were obtained. In February 2007, the F₁ seed were sown in a greenhouse, cultivated, and plant lines were produced with flower colors of blue, cream, and pink having a compact growth habit. In May 2007, a single plant was selected within the F₁ plants that had a pink flower color and a compact growth habit and designated ‘K2008-121’.

In July 2007, ‘K2008-121’ was vegetatively propagated, cultivated, and evaluated in Salinas, Calif. In October 2007, ‘K2008-121’ was confirmed to be fixed and stable. ‘K2008-121’ was further propagated and cultivated in February 2008 to reconfirm the line's stability. ‘K2008-121’ was subsequently designated ‘SAKCAL104’ and found to have its unique characteristics reproduce true to type in successive generations of asexual vegetative propagation via vegetative cuttings in Salinas, Calif.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Salinas, Calif.

-   -   1. Pink flower color; and     -   2. A compact plant growth habit.

DESCRIPTION OF THE PHOTOGRAPHS

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKCAL104’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on four-month-old plants grown under greenhouse conditions in Salinas, Calif. in the summer of 2012. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4^(th) edition (2001).

-   Classification:     -   -   Family.—Solanaceae.         -   Botanical.—Calibrachoa spp.         -   Common.—Calibrachoa.         -   Designation.—‘SAKCAL104’. -   Parentage:     -   -   Female parent.—Proprietary hybrid Calibrachoa line ‘6dw-54B’             (unpatented).         -   Male parent.—Proprietary hybrid Calibrachoa line             ‘5Bdw-70A-1C’ (unpatented). -   Growth:     -   -   Time to produce a rooted cutting.—About 6 weeks.         -   Environmental conditions for plant growth.—The terminal 1.0             to 1.5 inches of an actively growing stem was excised. The             vegetative cuttings were propagated in five to six weeks.             The base of the cuttings were dipped for 1 to 2 seconds in a             1:9 solution of Dip 'N Grow (1 solution: 9 water) root             inducing solution immediately prior to sticking into the             cell trays. Cuttings were stuck into plastic cell trays             having 98 cells, and containing a moistened peat moss-based             growing medium. The cuttings were misted with water from             overhead for 10 seconds every 30 minutes until sufficient             roots were formed. Rooted cuttings were transplanted and             grown in 20-cm diameter plastic pots in a glass greenhouse             located in Salinas, Calif. Pots contained a peat moss-based             growing medium. Soluble fertilizer containing 20% nitrogen,             10% phosphorus and 20% potassium was applied once a day or             every other day by overhead irrigation. Pots were             top-dressed with a dry, slow release fertilizer containing             20% nitrogen, 10% phosphorus and 18% potassium. The typical             average air temperature was 24° C. -   Plant description:     -   -   Habit and form.—Compact and branching.         -   Life cycle.—Tender perennial.         -   Height (from soil line to top of foliage).—8.0 cm.         -   Spread.—35.0 cm.         -   Flowering requirements.—Will flower so long as day length is             greater than 12 hours and temperature is above 13° C.         -   Temperature tolerances.—Excellent resistance to rain, heat,             and drought.
